Marcel reads 20 pages every other day Xion reads 8 pages every day Amber reads 56 pages every 7 days Francessca reads 55 pages every 5 days Which one of these will get to 350 pages first? State the number of days they will take to complete it.
Answers
Answer:
Marcel reads 20 pages every 2 days.
Then, in one day, she reads:
20/2 = 10 pages per day.
Now, we know that in one day she reads 10 pages, then we can subdivide the number 350 in N groups of 10 pages, each one of these N groups needs one day to be read, then 350 pages will be read in N days:
N = 350/10 = 35 days.
Xion reads 8 pages per day.
Then to read 350 pages, he neds:
N = 350/8 = 43.75 days
Amber reads 56 pages in 7 days.
Then she reads 56/7 = 8 pages per day (Same as Xion)
Then she also needs 43.75 days to read 350 pages.
Francessca reads 55 pages in 5 days.
Then she reads 55/5 = 11 pages per day.
To read 350 pages, she needs:
350/11 = 31.82 days
Then the one that needs less days to read 350 pages is Francessca.

What is coordinate?A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more integers, or coordinates. It matters how the coordinates are arranged.
Sometimes they are recognised by their place in an ordered tuple, and other times they are recognised by a letter, such as "the x-coordinate." In elementary mathematics, the coordinates are assumed to be real numbers. Point A t represents (3, - ).

The slope is the intensity of inclination thus the slope of p(x) is greater than the slope of m(x) thus option (A) is correct.
What is the slope?A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.
As per the given function,
p(x) = 157.1x
p(x)/x = slope = 157.1
The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by
Slope = (y₂ - y₁)/(x₂ - x₁)
In the function m(x) the slope will be as,
Slope = (188.4 - 125.6)/(3 - 2)
Slope = 62.8
Hence "The slope is the intensity of inclination thus the slope of p(x) is greater than the slope of m(x)".

Okay so we are given (9 + 71) + (-5 - 31).
We need to figure out the value of this expression.
First, let's solve the expression (9 + 71).
1. (9 + 71) = 80.
Now we have 80 + (-5 - 31).
Next, let's solve the expression (-5 - 31).
2. (-5 - 31) = -36.
We're left with 80 + (-36).
Finally, let's add the two numbers together.
80 + (-36) = 44
So (9 + 71) + (-5 - 31) = 44

Answers
Answer:

Step-by-step explanation:
1/2(2-4x)+2x=13
We simplify the equation to the form, which is simple to understand
1/2(2-4x)+2x=13
Simplifying:
+ 0.5*(2-4x)+2x=13
Reorder the terms in parentheses
+(+1-2x)+2x=13
Remove unnecessary parentheses
+1-2x+2x=+13
We move all terms containing x to the left and all other terms to the right.
-2x+2x=+13-1
We simplify left and right side of the equation.
0x=+12
0=12
The left and right sides are not equal, therefore there is no solution. This equation is invalid.
